- In addition to the 403 error causes mentioned above, there are also a few things you can do to troubleshoot for Nginx 403 forbidden error.
- No index file defined – When there is no index file present in the directory defined with the index directive, this can result in an nginx 403 forbidden.
For example, consider the following index directive:
- Nginx will search from left to right for the defined index files. Starting with index.html and ending with index.php, if none of the defined files are found, Nginx will return a 403 error.
- IP based restrictions – Your nginx.conf file should also be verified to ensure you are not unintentionally denying a particular IP. Check the configuration file for directives similar to deny 192.x.x.x; which will block said IP from accessing a particular directory, website, or your complete server (depending on where you define it).
- Autoindex Off – With Nginx, if you don’t have an index file then a request gets passed on to the ngx_http_autoindex_module. If this module is set to off then you will likely receive a Nginx 403 forbidden error. Setting this module to on should resolve the 403 error. For example:
